more on Russ's study on lenses
Question...
Watching most of Russ;' videos I got hooked on the Learning Lab 170 book material he did with sooo much testing of lens...
Is there a PDF of his efforts compiled, ie. similiar to his folder/book he used in the video.
I really would like to spend some quality time personally with those data sheets...
Thanks to Russ of course for his continuous efforts on investigation, being a design engineer also, his data gathering is addictive to review.
